Specification of Letters Patent. Patented llIal. 25, 1919.

Application led August 17, 1916. Serial No. 115,363.

T0 all whom it may concern.'

Be it known that I, GILMORE M. Yos'r, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Vises, of which the following is a full, clear, and eXact description.

This invention relates to vises, particularly wood workers vises, and has especial reference to the so-called universal and quick acting vise, the jaws of which can be turned and tilted and,`in fact, given a substantially universal movement with respect to the bench or other support on which the device is mounted, and the movalble jaw of which can be adjusted by the regular screw or can be released and slid bodily in or out relative to the normally stationary jaw.

The present application covers a modification of the vise shown in a companion application, Serial No. 115,362, filed of even date herewith, and in which certain features are more broadly claimed than herein, the object of the present invention being to provide certain improvements which increase the efliciency and durability of vises of this character, and also to provde more efficient means for effecting the various adjustments or movements, especially the means for engaging and disengaging the nut and screw so as to permit the front jaw to be shifted either by the screw-adjusting means or to be bodily slid in or out toward or from the relatively stationary jaw.

The present construction differs from that shown in the companion application largely in the form and shape of the guide which extends from the front Vjaw through the rear jaw, and in the arrangement and disposition of the nut which engages the screw, and of the cam rod which is designed to be turned to cause the nut to engage or move out of engagement with the feed screw.

The invention herein may be briefly summarized as consisting in certain novel details of construction and combinations and arrangements of parts which will be described in the specificationV and setforth in the appended claims.

In the accompanying sheet of drawings, Figure 1 is a top lan view with the vise detached from the ench and with the supporting 'bracket for the brace rod in section; Fig. Q.. is a side elevation'of the same with the bench shown in outline section;

Fig. 3 is a top plan view of the major portion of the vise with parts broken away, the vise being shown detached from the bench; Fig. 4 is a plan view of the major portion of the rear jaw and parts immediately associated therewith, portions being broken away and the annular split bearing and annular projection on the jaw which fits'therein being in section substantially along the line 4 4 of Fig. 6, looking in the direction indicated by the arrow; Fig. 5 is a partial side view and partial vertical Sectional view, the section being taken longitudinally through the vise and indicating in outline the bench or other support to which the vise is here shown attached; Fig. 6 is a transverse sectional view substantially along the line 6-6 of Fig. 5, and Fig. 7 is a front view with the cap or cover removed from the movable jaw and with the screw and operating handle in section; Fig. 8 is a partial elevation showing a detail of construction. Y The vise includes a rear jaw 10 which is normally stationary, and a front relatively movable jaw 11. The jaws and in fact the vise as a whole, is adapted to be secured to a bench 12 or other suitable support by a pair of hinged members including a hinge leaf 13, which is designed to be secured to, the upper face and front edge of the bench, and a second hinge member 14, which is pivoted to the first by a pivot pin or similar securing means 13, The hinge member 14 is provided beneath the bench with a rearwardly turned cylindrical split clamping and supporting or bearing sleeve 15 which can be loosened or tightened by a clamp lever 16 and receives a rearwardly extending annular boss 17 on the rear jaw 10. The construction is such that when the bearing sleeve is loosened, the jaws and parts which are associated therewith may be turned to any desired angle, and when the split sleeve is tightened the parts will be held firmly in the adjusted position.

The front jaw is in this case composed of two relatively movable parts by which the jaw proper may be tilted with reference to the fixed jaw so as to cause the adjacent faces of the jaws to assume an angular po- 'sition instead of the parallel relationship.

vise, the brace rod 32 is released by opening the split clamping sleeve 35, and after the vise has been tilted o1' adjusted to the desired position the sleeve is tightened on the rod by the clamp lever 38. The rod then holds the vise firmly in position.

Preferably the major middle portion of the front jaw including the forked head 19 is inclosed in a cover plate 39.

The construction above described is durable and at the same time it is very convenient, for the-vise as a whole can be turned about the axis of the hinged members 1.3 and 14; both jaws and the guide beam 22, screw 23 and cam shaft 27 may be turned in the split bearing 15 to any desired position; the parts of the front jafw may be turned relative to each other, and by means of the nut and screw releasing mechanism the front jaw can either be moved slowly by means of a screw or it can be slid in or out with reference to the rear jaw, this releasing mechanism being particularly eiicient, durable and convenient of operation.

Having described my invention, I claim 1. In a vise, a pair of jaws including a rear normally fixed jaw and a. front movable jaw, a hollow rectangular guide beam extending from the front jaw through the rear jaw, an annular bearing for the jaws, an annular support for the rear jaw and received in said bearing whereby both jaws may be turned about the laxis of the bearing, a feed screw extending from the front jaw and through the said guide beam longitudinally thereof, a1 nut within the said beam and adapted to engage the feed screw, the said nut being movable with the guide beam, said guide beam being formed with a longitudinal slot, a cam shaft extending lengthwise of the beam and occupying said slot, said cam shaft engaging the nut and moving the same into engagement with the said feeding screw, the cam shaft when turned in one direction releasing the nut from the screw.

2. In a vise, a pair of jaws including a rear normally fixed jaw and a front movable jaw; a: hollow rectangular guide beam extending from the front jaw through the rear jaw; an annular bearing for the jaws, an annular support on the rear jaw which is received in said bearing, whereby both jaws may be turned about the axis of the bearing; a feed screw extending from the front jaw through thehollow guide beam and longitudinally thereof, said guide beam being formed with a slot in the lower portion thereof, a nut mounted within the said guide beam and adjacent the said slot, said nut being adapted to engage the feed screw and movable to and from the same, a cam shaft extending lengthwise of the beam within the said slot in the guide beam and beneath the nut said cam shaft being adapted to be turned to move the nut to engage the feed screw or to release the nut from the screw.

3. In a: vise, a pair of jaws including a rear normally fixed jaw and a front movable jaw, a hollow rectangular guide beam extending from the front jaw through the rear jaw, an annular bearing for the jaws, an annular support on the rear jaw which is received in said bearing whereby both jaws may be turned about the axis of the bearing, al feed screw extending from the front jaw through the hollow guide beam and longitudinally thereof, said guide beam being formed with a slot in the lower portion thereof, a nut mounted within the said guide beam and adjacent to the said slot said nut being adapted to engage the feed screw and movable to and from the same, a cam shaft extending lengthwise of the beam within the said slot in the guide beam and beneath the nut, said cam shaft being adapted to be turned to move the nut to engage the feed screw or to release the nut from the screw, and spring means engaging the said nut to move the nut away from the feed screw when the nut is released by the cam shaft.

In testimony whereof, I hereunto affix my signature.
